6 3 Description of the device bon CP-33 ID 3 Description of the device The CP-33 ID chart projector has a total of 32 test fields to determine the visual acuities of the human eye. The individual charts are very clearly reproduced thanks to the special design of the optotypes and the high resolution lens system. All tests are conveniently controlled using the infrared remote control, with a switching speed of 0.03 seconds. The projector enables you to program two separate test series. The Landolt rings meet the requirements stipulated in DIN and EN ISO 8596 and can therefore be used for expert statements or for eye tests for admission procedures. The projector has four sets of charts Landolt rings in acuity levels 0.1 to 2.0 Numbers in acuity levels 0.05 to 2.0 Illiterate Es in acuity levels 0.1 to 2.0 Children s in acuity levels 0.1 to 1.0 Special features: Asticmatic fan test Red/green test Bichrome balance test Worth test Schober test Refraction balance test Heterophoria test Aniseikonia test (vertical) Aniseikonia test (horizontal) Stereo test GA bon CP-33 ID Rev 1.0 E doc 6/20

7 4 Safety instructions bon CP-33 ID 4 Safety instructions Please observe the statutory accident prevention regulations and the following safety instructions! Setting up and installation: The chart projector must not be operated or set up in damp conditions Avoid water splashing or spraying onto device Connect the device to a properly installed mains socket or power supply, e.g. on a testing unit (230V ). Operating: The chart projector may only be operated by suitably trained staff. Do not expose to extreme temperatures. The recommended temperature range is between +10 C and +40 C. The chart projector is not designed to be operated in areas where there is a risk of explosion. Do not place any objects on the ventilation vents on the casing. This causes the projector to heat up and can destroy it. Do not insert any objects on the ventilation vents on the casing. Do not look directly into the projection lens, as this may damage the eyes. Other information: To unplug - do not pull the cable; pull the plug itself. Ensure that the cable is not damaged (e.g. sharp edges or heat). Disconnect from power supply prior to carrying out repairs, servicing or maintenance work. GA bon CP-33 ID Rev 1.0 E doc 7/20

8 5 Setting up and operating bon CP-33 ID 5 Setting up and operating 5.1 Setting up Depending on the accessories, the chart projector can be mounted on a stand, wall mounted or set up on a testing unit column Direct projection of the projection screen supplied Note 1. The patients eyes and the projection screen must be at the same height to ensure that the chart is always the right size for the patient and is always at the correct angle. 2. The installed projector must always be placed to the side of the patient and usually differs in height. Adjust the projection screen according to the angle and to ensure maximum reflection of the projector light. 3. Ensure that the distance between the patients eyes and the projection screen (projection distance) is at least 4 m. 5 to 6 m distance is standard 4. Ensure that the patient is looking straight through the testing glasses and not at an angle, e.g. a phoropter in the centre of the projection screen. 5. If using other projection screens ensure that the light density of the testing field is 80 to 320 cd/m², as stipulated in ISO EN Projector Projection screen Patient s eye Projection distance Figure 5-1: Direct projection (top view) GA bon CP-33 ID Rev 1.0 E doc 8/20

9 5 Setting up and operating bon CP-33 ID Projection via a mirror system If it is not feasible to observe the minimum distance of 4 m, projection can be achieved using a system of mirrors (not supplied). Two surface mirrors with angle hinges are required. Please observe the information in To achieve maximum reflection, to set up the surface mirrors (A and C) place a smaller plane mirror on the projection screen (B), taking care not to damage the projection screen. Projection distance: a + b = S1 + S2 = S3 + S4 S4 S3 S2 S1 Figure 5-2: Indirect projection (top view) GA bon CP-33 ID Rev 1.0 E doc 9/20

10 5 Setting up and operating bon CP-33 ID 5.2 Operating Insert the supplied batteries into the battery compartment in the remote control. Use the power switch (2) to switch the projector on and off. The chart projector is now operational. Aim the remote control towards the chart projector and press any key. The projector lamp is activated and the corresponding sight test is shown on the projection screen. Focussing Turn the thumb wheel on the base of the casing (4) to focus the projected image.

Red/green test Bichrome balance test Worth test Schober test Refraction balance test Monocular spherical fine adjustment. Adjustment is complete when the red and green sections are the same. Binocular spherical fine adjustment with polarisation filters. One eye sees the fields on the right and the left and the other sees the fields at the top and bottom. Heterophoria and dominance test With red/green filters the white field is registered in both eyes (fusion). The coloured fields are registered in one eye. Red/green filters to determine heterophoria. Note: The results may be slightly falsified by the chromatic aberration. Checking the refraction balance with polarisation filters. Both eyes only register one line. Heterophoria test Polarisation filters to determine heterophoria. Vertical and horizontal lines are seen monocularly. Aniseikonia test vertical Aniseikonia test horizontal Stereo test Test with polarisation filters in a vertical direction to see if both retinal images are the same size. Test with polarisation filters in a horizontal direction to see if both retinal images are the same size. Test to determine the stereo threshold with polarisation filters.
